Overview
MATLAB Support Package for Arduino enables you to use MATLAB to communicate with the
Arduino board over a USB cable.
Simulink Support Package for Arduino enables you to convert your Simulink
models to code that runs on the Arduino board (in a click of a button).
This tutorial covers a step-by-step guide to:
MATLAB Support Package
1. Set up the MATLAB support package for Arduino
2. Send commands from MATLAB to Arduino to blink an LED
Simulink Support Package
1. Set up the Simulink support package for Arduino
2. Build a simple Simulink model for controlling pins on the Arduino
3. Generate, download and run code on the Arduino to blink an LED
This is the first tutorial in a series on using MATLAB and Simulink to program an Arduino. In
this tutorial Arduino Due is used as an example, however the same steps can be used for
other boards like Uno, Mega 2560 etc.

Build the circuit
Circuit
Use the following image to build a simple circuit that connects an LED to pin 9 of Arduino
Due.
Co nnect the hardware
Using the USB connector, connect Arduino Due to the computer that has a MATLAB &
Simulink installation.

Set up MATLAB and Simulink support package for
Arduino Due
Start MATLAB
Open MATLAB and click the Add-Ons drop down menu on the top right
Start Suppo rt Package Installer
Click on Get Hardware Support Packages in the drop down menu to start the installer. Select
'Internet' as a source for installing the support package
Select Arduino fro m a list o f suppo rt packages
Click Next to see a list of support packages and select Arduino from the list for MATLAB
Support Package and Arduino Due for the Simulink Support Package.

Set up compiler support
Install a suppo rted co mpiler
Simulink support package for Arduino is supported on 32-bit and 64-bit Microsoft Windows
and Mac OS X. For the code generation process to work, a supported compiler installation is
required. Refer to the following page on MathWorks website for a list of supported
compilers on Windows and Mac OS:
List of supported compilers (http://adafru.it/eof)
For example, you can download a Simulink supported compiler from the Microsoft
website (http://adafru.it/d5J) for free.
Co mpiler set up in MATLAB
Enter mex -setup at the MATLAB command prompt to start the compiler set up. When the
compiler set up is complete, you should see on MATLAB Command Window the compiler
being used.

Simulink model
Open a Simulink demo mo del
Enter arduinodue_gettingstarted at the MATLAB Command Window to open a demo
model. Again, in this tutorial Arduino Due is used as an example but the same steps can be
used for other boards like Uno, Mega 2560 etc.
Double-click the Pulse Generator block to explore its pre-configured parameters. The Digital
Output block is set up to send the output of the Pulse Generator to pin 9 of the Arduino Due.
Double-click the block to explore its pre-configured parameters.
You are now ready to program Arduino boards!
Optio nal - Create the mo del o n yo ur o wn
Click on the Simulink Library icon to open the Simulink library browser
In the left navigation pane, select Simulink Support Package for Arduino Hardware
On the right navigation pane, double-click the [Examples] block to open the
documentation

Generate code, Load and Run
If you opened the demo model, you can go straight to Run the model on Arduino section. If
you followed the steps to create your own model, then to configure the model for Arduino
boards follow this section.
Prepare the mo del to run o n Arduino bo ards
Connect the Arduino board to your computer with a USB cable
Select To o ls > Run o n Target Hardware > Prepare to Run...
Review the parameters in the dialog that opens
Unless already set, set the Target hardware parameter to the Arduino board being
used (Arduino Due here)
Do not change any other settings
Click OK
Save the model
Run the mo del o n Arduino
Click on the 'Deploy to Hardware' button as shown in the figure below
You should see the LED on Pin 9 blinking
